Data centres are causing an increase in global energy demands. To prevent this new energy demand increasing CO2 emissions, data centres need to shift from being consumers to active prosumers. Policies and technologies to support this shift across computing, electrical and thermal energy systems will be crucial for reducing the energy consumption and emissions of data centres.
